Title: Golf club head
Inventor: SHIMIZU TETSUO
IPC: A63B102/32
Filed: 1991-12-29
Abstract: PURPOSE:To improve the directivity of a driven ball by making the curvature at the high-speed point on the face surface larger than the curvature at the low-speed point so that the flight direction is not drifted horizontally or vertically when the ball is driven at any point on the face surface. CONSTITUTION:In a golf club head 1 formed with the face 2 surface into a protruded curved surface, the angle theta at the point satisfying V1>V is set larger than the angle theta at the point satisfying V1<V, where V is the speed of the sweet spot S when a ball is driven, V1 is the speed of an optional point T on the face 2 surface other than the sweet spot S when the ball is driven, and thetais the angle between the normal line at the sweet spot S and the normal line at the optional point. The spin of the ball 3 driven by a high-speed face surface portion F is increased by a large gear effect, however the correcting effect of the flight direction of the ball 3 after it is driven is increased because the curvature of the portion F is large, and the directivity is improved.

IPC: H04N1/21
Filed: 1998-12-22
Abstract: PROBLEM TO BE SOLVED: To enable fast printing with high quality while preventing overrun without an expensive mass image memory. SOLUTION: Printing data (image data) are received from a host computer and image data for a piece of paper are prepared on an image memory.
